Help me identify a pressure sensor? - Electronic Circuits Projects Diagrams Free

Is there a 0-100PSI liquid pressure sensor that is fairly equivalent to the LM34 temperature sensor in price, linearity, and voltage range? (in other words, ease of use?) Ideally it would have a +10 mV/PSI scale factor.

I've been all over digikey, mouser, newark, and others.. but there are roughly twenty million devices to choose from.

Thanks.

I just bought two of the MPX5700GP-ND's.
(About $17.00 each)
0 to 700 KPA or 0 to 101.5 PSI.
They seem to work quite nicely in a suitable circuit.
